In metal oxide, O 2 - ions are arranged in hcp lattice while metal ions occupy 2 3 r d of octahedral voids. The simplest formula of oxide is

Number of O 2 - ions = n Number of octahedral voids = n Number of M n + ions = 2 3 n Ratio of M and O = 2 3 n : n = 2 : 3 So simplest formula of solid = M 2 O 3 .

In metal oxide, $O^{2 -}$ ions are arranged in hcp lattice while metal ions occupy $\frac{2}{3} r d$ of octahedral voids. The simplest formula of oxide is

Options:

Answer:

Solution:

Number of $O^{2 -}$ ions = n
Number of octahedral voids = n
Number of $M^{n +}$ ions $= \frac{2}{3} n$
Ratio of M and $O = \frac{2}{3} n : n$
= 2 : 3
So simplest formula of solid $= M_{2} O_{3}$ .
